IMPROVED NEEDLE MACHINE.

TO ALL PERSONS TOWVHOM 'THESE PRESENTS MAY4 COME: v

Be it known that I, WALTER AKEN, of Franklin, in the county of Merrimac, and State of New Hampshire, have invented a new'and useful Machine for Pointing or Rounding those Portions of Needles of Knitting Machines which are to compose the Hooks of such Needles, my said'machine being useful for pointing or rounding various other articles of wire; and I do hereby declare the same to be fully described in the followingspecification, and represented in the accompanying drawings, of which- Figure 1 is a top view, and

Figure 2 a longitudinal and vertical section of the machine.

Figure 3 is a top .view of its point-forming rest.

Figure 4 is a side view of a needle-blank as it appears preparatory to being rounded by the machine, the part z thereof to be rounded being square, or about so, in transverse section.

Figure 5 is a side view of such needle-blank, as it appears after having been treated by the machine, the part z in such case being circular 4in transverse section. v

In such drawings, A denotes a bar or cutter-wheel xed upon a rotary shaft, B, duly supported by a standard, O, which is erected on the bed-plate D of the machine. The shaft B may have a pulley or driving-wheel, 'a,

xed to it for putting it in revolution bymeans of an endless belt going around such pulley. Underneathr the said cutter-wheel is an adjustable rest, E, in whose upper surface is a groove, provided with a flaring mouth, c, such groove having the form of the counterpart or half of the point to be made upon the needle-blank. The lrest E is supported within the standard C, and provided with a clamp-screw, d, and an elevating-screw, e, they being screwed into the standard, and arranged in manner as represented in the drawings. 'lhe cutter may be grooved on and entirely around its periphery, if desirable. When so grooved it aids in keeping the needle blank in place in the rest. A long shaft, F, is arranged underneath the rest E, and at right angles with the shaft of the cutter, the plane of rotation of such cutter being inv line with the axis of the shaft F. The said shaft Fis supported by and So as to be capable of being revolved, and alsoslid longitudinally within.A two standards, Gr G, erected on the base-plate. The shaft F is also connected with another or driving-shaft, H, by

two gears,fg, the smaller of which is fixed to the shaft H, and is wider than the larger, which is attached to the shaft F. A rotary wheel, I, provided with a series of arbors, K K K K, turns on the shaft F, and is arranged o n such shaft, `and against a collar, h, fixedthereto, the whole being as represented. The several arbors are horizontal, and disposed at equal distances apart, and each has a small pinion, z', fixed on its rear end. Each' arbor, .at its front or opposite end, is socketed, to receives. needle-blank, and is providedwith-a sliding collar', 7c, which slides lengthwise on the arbor, and carries a clamp, Z, and a clamp-screw, m, the whole being as shown in the drawings. Directly over the path of movement of the several pinions 7.', is a long gear, m2, which engages with the uppermost of such pinions, and isiixed on a shaft n, provided with a driving-pulley, o, and supported by a standard, p, erected on the base-plate. A wheel, g, arranged alongside of the wheel I, is fixed to vthe shaft -F, and contains a conical recess, r, or its equivalent, to receive and bear against a cone, r', made on the rear face of awheel, I, the same being to cause the wheel by friction of the surface of the cone and recess to revolve with the shaft when such wheel is not locked in position by a bolt, s. The said bolt, in order to so` lock the wheel, enters one of a series of holes, t,made in the wheel, at equal distances asunder, and in number corresponding with that of the arbore of such wheel. yThe said bolt, arranged as represented in fig. 2, is shot forward by a spring, u, and drawn back by a cam, v, the latter being xed upon the shaft F. A cam, w, fixed on the shaft F, and properly shaped, serves to move such shaft backward. A helical spring, w', encompassing such shaft, and acting against the cam 'w `and the 'next adjacent shaft-supportingstandard, is employed to advance the shaft. The cam w acts against a friction-roller, x, supported by a standard, y, erected on the face-plate.

When the machine has its arbore supplied with needle-blanks to be pointed or rounded or reduced, and the several driving-shafts are put in'revolution, the blanks will be successively introduced and moved between thc rest and its rotary cutter, and by the letter will be rounded or reduced, and after each of the blanks may have been soreduced, it will be drawn back from between 'the rest and cutter, the wheel I will be .unlocked and pari tially revolved, and Aagain locked, so as to bring a succeeding blank up to the cutter and rest. The rest E supports the blank while being advanced and revolved. The cutter, by cutting in a direction lengthwise of the blank, while the latter` is in revolution, acts on the blank in a. manner to prevent it from being sprung out of its groove in the rest.

What I elam as my invention, is

The machine or combination, substantially as descrided, for the purpose set forth, that is, as composed of the rotary cutter A, the grooved rest E, the series of rotary urbors K, their carrier or Wheel I, and operative mechanism, the shaft F, and the meehanism for revolving und moving it longitudinally, and-the bolt s, and

mechanism for operating such bolt, substantially as explained.

WALTER AIKEN.
